ADOLPI-I PLAGMAN, OF DAVENPORT, IOWA, ASSIGNOR TO WHITE LILY MANUFACTUR- ING COMPANY, OF DAVENPORT, IOWA, A CORPORATION OF IOWA.

MECHANICAL MOVEMENT.

To all whom it may concern:

Be it known that I, ADoLrH PLAGMAN, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Mechanical Movements, of Which the following is a full, clear, and exact description.

The object of my invention is to provide a simple mechanical movement for converting a continuous rotary motion into a rotary reciprocal motion by means, the reversing action of which is accomplished in a novel manner that makes it less abrupt and with less friction than has heretofore been accomplished, substantially as hereinafter fully described and as particularly pointed out in the claims.

In the drawings z-Figure l is a side elevation of my invention having a portion broken away. Fig. 2 is a plan view with part of the supporting-frame broken away. Fig. 3 is a diagrammatical view showing a side elevation of the converting mechanism in one extreme position. Fig. 4 is a corresponding view showing said mechanism in the opposite extreme position. Fig. 5 is a plan view showing the connecting mechanism at one extreme position.

In the drawings A represents the support for my improved mechanical movement, and B the rotary reciprocal or driven shaft. This shaft, B, extends up through a suitable bearing a made integral with the lower segment of a ring-shaped annular supportingframe C, and up through a diametrically opposite bearing Z), made in the uppermost segment of said annular frame and has a cotter c through its upper end to secure the same in place. Between these bearings, shaft B is provided with a longitudinal groove d, and has mounted thereon a longitudinally reciprocal sleeve D, that is provided with a suitable feather or spline that enters said groove d; thus permitting the longitudinal movement of said sleeve, but preventing its rotating independently of said shaft. About midway its length, sleeve D is provided with a segmental rack E projecting at right angles from its circumference. This rack consists of a number of equi-distant spokes or arms that are connected by a suitable rim, substantially as shown, and it is engaged by a spur-gear or pinion F on the adjacent end Specification of Letters Patent.

of drive-shaft G; which latter extends at right angles to shaft B, out through a suitable bearing e made in the annular frame C midway between the bearings of shaft B, and through bearing f in the end of an extension g of frame C, and has on its outer end a drive-wheel I-I, that may be driven by hand or otherwise.

Shaft is revolved continuously in one direction, and the pinion F which engages the rack E rotates the latter, together with shaft B, until it reaches the end of the rack, whereupon, by virtue of the assistance received from other mechanism, supposing the rack to have been moving in a plane below it, it will lift said rack and sleeve until said rack will be in a plane above the pinion. The continued rotation will then move the rack in the opposite direction until its opposite end reaches the pinion where it will engage the mechanism her'einbefore mentioned, and will gravitate to its lower position again. The reverse of this operation is the same when the drive-shaft G is revolved in the opposite direction.

In order to limit t-he movement of the rack, I provide a reversing-frame I, or yoke, the body of which is parallel to the axis of shaft, B, and located on the side thereof opposite the rack. The ends of this reversing-frame are bent at right angles to its length to form pivotal lugs It, h which are loosely journaled on shaft B next its bearings. Midway between its pivotal lugs this reversing-frame is made annular in construction to provide a circular or other suitably shaped opening or eye, J, out through which a stud K, projecting diametrically opposite rack E, extends. The upper and lower ends of the reversing-frame, I, are provided with oppositely projecting` wings y', j, and lc, 7c, respectively, which are adapted to engage first one side and then the other of stop-lugs, m, and n, projecting toward the axis of the drive-shaft G from the annular-frame, C, near the bearings of shaft, B, in a vertical transverse plane just beyond the face of the pinion Il opposing sleeve D. The vertical dimensions of the opening, J, of the reversing-frame, I, correspond to the throw of the reciprocal sleeve D plus the diameter of the stud K, and for convenience of construction I prefer to make it substantially circular.

In operation, as the point of engagement of pinion F approaches the ends of the rack, the stud K moves in the eye of the reversing frame, J, in the same direction with it, until the wings y', 7c, projecting from the ends of the reversing-frame, in the direction in which the stud is moving, engage'the stops,

m, and n', whereupon said stud is compelled' to roll up the side of the circumference of the eye by the engagement of the pinion with the end cog or spoke of the rack. Then the rack reaches the plane above the pinion, and begins to move in the opposite direction, it will momentarily, and while it is moving in the upper quadrant of the eye, let the reversing-frame remain stationary. lVhen the stud reaches the limit of its upward movement it again engages the reversing-frame and moves the same in the opposite direction until the wings j, projecting opposite fromthose last mentioned, engage the opposite sides of the stops fm, and n, whereupon the stud moves downward with the rack E, and holds the same and pinion F, in engagement while the former is moving downward. The reversing-frame, J, remains stationary while the stud is in engagement with the lower quadrant of the eye rwhile describing its downward movement. Thus the reversing-frame J has an intermittent rotary reciprocal motion, the extent of which is less than that of the rack, and reduces the friction of the mechanism during the reversing movement or operation of the converting mechanism and makes it much easier to operate.
